    (2015-09-01) TATLI, Emel; Gursu, MELTEM; Aydın, Zeki; UZUN, Sami; KARADAG, Serhat; CEBECI, Egemen; PEHLIVANOGLU, Filiz; SAVAS, Ozturk; Kazancioglu, RÜMEYZA; GÜRSU, MELTEM; KAZANCIOĞLU, RÜMEYZA
    Peritonitis still maintains its importance today as the most significant complication affecting mortality and morbidity in peritoneal dialysis (PD) patients. Although peritonitis is bacterial in 80% of cases, increasing rate of fungal peritonitis has been reported by many studies in recent years. While Candida species (mainly C. parapsilosis, C. albicans and C. tropicalis) are responsible for 70% of cases, other species (Trichosporon, Penicillium, Aspergillus and Acremonium) are very rarely seen. C. guilliermondii has been reported as the cause of peritonitis in PD patients in a few cases. Herein, we present a PD patient with peritonitis due to C. guilliermondii. We aimed to emphasize that non-albicans Candida species should be remembered in PD patients with peritonitis.

    Is handgrip strength and key pinch measurement related with biochemical parameters of nutrition in peritoneal dialysis patients?
    (2015-07-01) YARDIMCI, Bulent; SUMNU, Abdullah; KAYA, Ibrahim; Gursu, MELTEM; Aydın, Zeki; KARADAG, Serhat; UZUN, Sami; tatlı, Emel; OZTURK, Savas; CETINUS, Ercan; Kazancioglu, RÜMEYZA; GÜRSU, MELTEM; KAZANCIOĞLU, RÜMEYZA
    Backgrounds & objective: End-stage renal disease (ESRD) frequently causes Protein Energy Wasting (PEW), which is an important morbidity and mortality factor. Although it is difficult to assess PEW with a reliable method, there are various methods such as Handgrip strength test (HST), serum albumin, cholesterol, etc. HST is a simple and reliable antropometric method which is used for nutritional status and body muscle strength. This study aims to assess the relationship between HST and biochemical markers in evolution of nutritional status of ESRD patients. Methods: This cross-sectional study included 36 consecutive patients, who are on peritoneal dialysis and 36 healthy -control subjects. Jamar-hand dynamometer was used for handgrip strength test; a pinch gauge was used for key pinch. Other antropometric tests included skin fold thicknesses at biceps, triceps, umbilical, suprailiac and subscapular regions; circumferences at waist hip, neck and midarm. Biochemical tests were performed only in Peritoneal Dialysis (PD) group. SPSS for Windows ver. 15.0 was used for statistics. Results: The mean age of patients was 49.3±14.4, and mean age of control group was 43.8±10.6 (p=0.075). In PD group dominant hand dynamometer test 1,2 and 3 results were 19.3±9.3 kg, 25.3±10.8 kg, 25.5± 10.6 kg and; 34.2±10.3 kg, 34.4±9.8 kg, 34.6±10.0 kg for control group (p< 0,001). Right key pinch results were 6.7±1.9 kg for patients; 13.5±4.5 kg for control group (p<0.001). Left key pinch results were 6.8±1.9 kg for patients; 13.2±4.4 kg for control group (p<0.001). There was not any significant relationship concerning handgrip or key pinch tests with biochemical parameters. Conclusion: Handgrip Strength Test and key pinch may be reliable, cheap and easily performed tests for the diagnosis of Protein Energy Wasting in patients on Peritoneal Dialysis.

    Relationship of ADMA Levels with Cardiovascular Parameters in Patients with Peritoneal Dialysis: A Bioimpedance Analysis Study
    (2018-12-01) Sumnu, Abdullah; CEBECI, Egemen; OZTURK, Savas; Gursu, MELTEM; KASAPOGLU, Ergun; OZKAN, Oktay; gümüş, Alper; Gurdal, Ahmet; KARADAG, Serhat; KUMBASAR, Abdulbaki; Kazancioglu, RÜMEYZA; GÜRSU, MELTEM; KAZANCIOĞLU, RÜMEYZA
    Objective: Asymmetric dimethylarginine (ADMA) is known as a non-traditional risk factor for cardiovascular disease. Considering the increased prevalence of hypervolemia and heart failure in patients with peritoneal dialysis (PD), we aimed to investigate the relationship of ADMA with other biochemical parameters, echocardiographic findings, and results of bioimpedance analysis, which is a method for the determination of body fluid distribution in detail.

    Volume status in patients on peritoneal dialysis: the role of apelin and bio-impedance spectroscopy
    (2012-01-01T00:00:00Z) Kazancioglu, RÜMEYZA; Gursu, MELTEM; KARADAG, S; TATLI, E; AYDIN, Z; UZUN, S; SUMNU, A; CEBECI, E; OZTURK, S; KAZANCIOĞLU, RÜMEYZA; GÜRSU, MELTEM
    One of the main factors determining the survival of peritoneal dialysis (PD) patients is volume status. We aimed to investigate hydration status of PD patients by bio-impedance spectroscopy (BIS) and echocardiography and to study the relation of them with apelin, which has effects related with volume status like vasodilation, positive inotropism, and inhibition of ADH release and RAS antagonism. Chronic PD patients without active cardiac disease or clinically prominent hypervolemia were included. Besides the demographic, clinical, and laboratory data, BIS and echocardiographic findings together with apelin levels were recorded. The study included 21 patients. Of them, eight patients were euvolemic, one patient was hypovolemic, and others have some degree of overhydration (1.1-6.8 L) with BIS, although all were euvolemic clinically. Mean apelin level was 1.49 +/- 0.49 ng/mL. Apelin level was positively correlated with ejection fraction and negatively with total body water (TBW), intracellular and extracellular water, lean tissue mass, and left atrium diameter. On linear regression model, TBW was the major determinant of apelin. Although apelin is expected to increase in hypervolemic patients, the negative correlation with body water in this study may be related with yet unknown role of apelin in dialyzed patients. They may have important roles in volume status in future.

    (2019-01-01) Gursu, MELTEM; ARICI, MUSTAFA; Ates, Kenan; Kazancioglu, RÜMEYZA; Yavas, Pinar Guneser; Öztürk, Murat; ALTUN, BÜLENT; Arinsoy, Turgay; GÜRSU, MELTEM; KAZANCIOĞLU, RÜMEYZA
    Background/Aims: Refugee dialysis is a worldwide growing dilemma with limited experience. This report presents the largest hemodialysis (HD) patient registry data of Syrian refugees in Turkey. Methods: Demographic, clinical, laboratory, and dialysis practice data of 345 Syrian HD patients during one year were collected and analyzed. Results: There were 345 prevalent Syrian HD patients at the end of 2016. Majority of the patients were placed in the Southeast Anatolian Region. The majority of the patients (74.8%) are in the age range of 20-64 years. Dialysis vintage in Turkey is less than 12 months in 20.8% and less than one month in 29.3% of patients. The vascular access was arteriovenous fistula in the majority of patients (72.5%). Kt/V is over 1.7 in 57%, serum albumin is above 35 g/L in 65.8% and hemoglobin level is more than 100 g/L in %65.2 of the patients. The ratio of patients with serum phosphorus level of 1.13-1.77 mmol/L was 56.2%. Twenty Syrian HD patients (14 male, 6 female) died within the year 2016 and annual mortality rate was 5.7%. Conclusion: This study with the largest number of Syrian refugees undergoing maintenance hemodialysis showed good dialysis practices, acceptable values for dialysis adequacy and biochemical parameters along with lower mortality compared to native HD population of Turkey. Longer follow up will enrich the knowledge related to care of refugee population in all over the world.

    (2017-03-01) Gursu, MELTEM; UZUN, Sami; Kazancioglu, RÜMEYZA; OZTURK, Savas; GÜRSU, MELTEM; KAZANCIOĞLU, RÜMEYZA
    Acute kidney injury (AKI) and chronic kidney disease (CKD) have many common points regarding risk factors, etiology, clinical and laboratory factors. We aimed in this review to discuss the outcome, the risk of CKD, cardiovascular and overall mortality risk after AKI, and the mechanisms underlying the relationship between AKI and CKD.
